You do realize as you grow older that almost nobody knows what they are talking about.

Our knowledge can only be finite, while our ignorance must necessarily be infinite.

The idea that you have to be protected from any kind of uncomfortable emotion is what I absolutely do not subscribe to.

It would be the height of absurdity to label ignorance tempered by humility "faith"!
(Institutio III.2.3)

Only a blind man can easily define what light is. When you do not know, you are bold. Ignorance is always bold; knowledge hesitates. And the more you know, the more you feel that the ground underneath is dissolving. The more you know, the more you feel how ignorant you are.

Knowledge slowly builds up what Ignorance in an hour pulls down
